To ctZZ ZL'h-OYJL it may concern.-

Be it known that I, NEPHI PACKARD, of Springviile, in the county of Utahand Territory of Utah. have invented certain new and useful Improvementsin Churns, of which the following is a specification, reference beinghad to the accompanying drawings.

The object of my invention is the production of a rotary churn adaptedby reason of its novel construction to expedite the operation ofchurning and to facilitate the removal of the product.

In the accompanying drawings, Figure .l is an elevation of my churn,illustrating the means of securing the cover. Fig. II is a similar viewshowing the side of the churnbody broken away. Fig. III is a top planview of my churn. IV is a detail view of the dasher, and Fig. V is aperspective of the lock-spring and cam-lever.

Referring to the figures on the drawings, 1 indicates the churn-body,which is preferably of cylindrical form, rcvolubly mounted in suitablebearings 2 by means of trunnions 3 projecting fromdianietrically-opposite sides of the churn-body and secured thereto bymeans of trunnion-plates i, as illustrated.

5 indicates a crank secured to the extremity of one of the trunnions forimparting rotary motion to the churn-body.

(3 indicates a cover provided with an annular recess 7 and a resilientband 8 secured therein adapted to rest upon a similar band 9 upon theupper edge of the churn-body. \Vhen the cover is in place, these bandsare adapted to afford a close connection between the cover and thereceptacle, and are preferably of soft rubber or similar material. Thecover is provided, preferably, with a somewhat convex upper surface, andis provided at its center with a metallic plate 11 and with radialplates 12 extendin g from the plate 1 l to the periphery of the cover.

it indicates a locking-spring tapering from its middle toward its endsand provided with a vertical longitudinal slot in which is piw oted acam-lever 15, provided with a handle 16 and cam 17. hen it is desired toclose the churn-body the cover is placed in posi tion and the lock-bar18 is placed thereon, its extremities extending through apertures 19 indiametricallyppposite cars 20 secured to the churn-body at its top, thecam-lever in this position being thrown back to the position indicatedby dotted lines in Fig. 1. It will be observed that the operator, bygrasping the lever and throwing it to the reverse position, will causethe cam to force the cover securely against the top of the churn-body,the spring-bar yielding sufficiently to allow the nose i l of the cam topass beyond the line of the pivot, when, as is evident, the resiliencyof the bar will lock the cam-lever and firmly secure the cover.

22 indicates a double dasher, consisting of two racks 23, composed ofvertical parallel strips 24 and transverse bars 25, the transverse barsof the two racks being placed alternately, the transverse bars of onerack being in the same horizontal plane as the space of the other rack.

20 indicates lugs upon the lower ends of the vertical rack-bars, adaptedto fit in the recesses 27 in the bottom of the body.

2% indicates tie-bars pivotally secured to the upper extremities of thevertical rackbars of one rack and provided at their opposite ends withtongues 29, adapted to fit in grooves 30 in the upper extremities of therack-bars of the other rack. The shoulders of the tie-bars are somewhatinclined, as illus- 'trated, to force the upper ends of the racks apartand securely wedge them within the churlrbody.

It is evident that the racks may be easily placed within the body, butthat when the tie-bars have forced them apart and wedged them securelyagainst the curvilineal sides of the receptacle, they are securelyfastened in place, the cover bearing against the tiebars and preventingtheir casual displacement. It is quite apparent, however, that as soonas the cover is removed the tie-bars may be lifted, allowing the racksto approach the center of the receptacle and to be easily removed.

' I do notdesire to limit myself to the details of construction hereinshown and described, but reserve to myself the right to change, vary,and modify the same within the scope of my invention.

I clainr 1. The combination with a cylindrical body part, of a pluralityof racks therein, tie bars pivotally secured to one rack and havingincline shoulders at their opposite extremities adapted to engage theopposite rack and Wedge said racks against the cylindrical body part,and a cover adapted to force the tie bars in place, substantially asspecified.

2. In a churn, the combination with a cylindrical churn body, of aplurality of racks therein consisting of vertical rack bars andtransverse rack bars located alternately, and

tie barshinged to the upper extremities of the vertical bars of one rackand provided with tongues adapted to engage grooves in the upperextremities of the vertical bars of the other rack, said tie bars beingprovided with inclined shoulders adapted to bear against the verticalbars of one rack to "Wedge the racks securely Within the churn body,substantially as specified.

3. The combination Withacylindrical body part, of a plurality of rackstherein, tie bars pivotally secured to one rack and adapted to engagethe opposite rack and Wedge said racks against the cylindrical bodypart, a cover adapted to force the tie bars in place,

a spring bar above the cover secured at its opposite ends to the churnbody, and a pivoted cam lever directly pivoted to the spring bar andengaging the cover to force the same against the tie bars, substantiallyas specified.

4. The combination with a cylindrical body part, of a plurality of rackstherein, tie bars pivotally secured to one rack and having inclinedshoulders at their opposite extremities adapted to engage, the oppositerack and Wedgesaid racks against the cylindrical bod y part, a coveradapted to force the tie bars in
